Figure 715 a top plan view of another form of An automatically operated stabilizing vane 31. submarine havingpropellers positioned at the is associated with each side of thesubmarine front and rear ends thereof; body 20 intermediate the ends thereof with said Figure 8 is a fragmentary horizontal sectional vanes located substantially midway the top and 55 bottom of the submarine, said vanes 31 being fixed to a pair of shafts 38 journalled in bearings 39 located interiorly of the submarine body, the inner ends of the shafts 38, each carrying a bevelled pinion 40 engaged with a bevel gear 4| that is automatically operated by a gyroscopic device 42 that is diagrammatically illustrated, the stabilizing vanes 31 operating to maintain the submarine body on an'even keel.

Sets of manually controlled vanes are arranged on the opposite sides of the submarine body, respectively forwardly and rearwardly of the stabilizing vanes 31 for controlling the underwater direction of travel of the submarine and as shown in Figures 1 to 3, a shaft 53 is journalled in bearings transversely of the submarine body 29 adjacent the forward end thereof with each laterally extending end of the shaft 43 carrying a vane 44 fixed to the shaft intermediate its ends. A pair' of vertically aligned horizontal shafts 55 and 46 is journalled transversely of the submarine body 20 rearwardly of the stabilizing vanes 31', the shafts 45 and. being connected together for simultaneous operation by link and arm devices 41 while a pair of arms 48 respectively carried by the shafts 43 and 45 are connected by a longitudinally extending link lfifor the simultaneous operaiion of the forward vane M and the double rear vanes 50 secured to the projecting ends of the rear shafts 55 and 86.

The operating means for the shafts 43, 45 and 46 is shown more clearly in Figs. 1 to 3 and includes a-worm shaft 5i journalled in bearings 52 with the operatin handle or wheel 53 therefor located in the cabin hood 25 in proximity of the operator's seat 54.

'armand link devices 41 to the shaft #35 for simultaneous operation of the vanes 44 and 5G for controlling the underwater direction of travel of the submarine.

The propeller blade 22 at the rear end of the submarine constitutes the main propulsion means therefor and a pair of propeller blades 51 respectively located at opposite sides of the front tapering and M of the submarine body and in propulsion of the submarine and are adjustable for cooperation with the side vanes 4 and 55 to add a direct propelling force to'the direction of under water travel of the submarine. As illustrated in Figs. 1 to 6, a shaft 58 extending transversely of the forward tapered end 2i of the submarine body is journalled in a pair of tubular bearings 59 which are in turn journalled in bearings 5% carried by the submarine body 20 and as shown more clearly in Figs. 1 and 5, a' bevel gear 6! is secured to the shaft 58 intermediate its ends and has the pinion 62 meshing therewith, said pinion 62 being carried by the shaft 53 of the motor 56.

' The-adjacent inner ends of the rotatable tubular bearings 59 have the side leg portions 65 of a U-shaped strap 66 anchoredthereto as at 61 for normally holding said strap and tubular bearings 59 againstv rotative movement while manually controlled devices are associated with said strap 66 for rotatably shifting the tubular bearings 59 and the propeller blades 51 carried by the outer ends of the tubular bearings.

As shown more clearly in Figures 1 and 6, a housing 68 is anchored to the outer end of each tubular bearing 59 and into which housings the The worm shaft 5! has a' worm portion 55 engaged with a worm segment outer ends of the shaft 58 respectively extend and carry a bevel gear 69. A propeller shaft 10 is journalled in the housing 68 transversely of the end of theshaft 58 and carries a bevel gear 1| meshing with the bevel gear 69, the propeller blade 51 being secured to the end of the shaft 10 projecting forwardly of the housing 58.

For holding the two housings 59 against rotative movement during operation of the shaft 58 for the operation of the propeller blades 51 and also for rotatably adjusting the tubular bearings 59 for changing the direction of propelling force of the propeller blades 51, devices are provided which are shown more clearly in Figs. 1, 3 and 4 and include a worm shaft 12 journalled in bearings 13 withinthe submarine body 20 and having an opcrating handle or wheel 14 at its upper end. The lower end of the worm shaft 12 carries a worm 15 that is engaged with a worm segment 16 secured to one of the side legs 65 of the U-shaped strap 66 at the point 11 with the shaft 58 journalled to said worm segment 16 as illustrated. It will be understood that when the worm shaft 12 is rotated, corresponding movement is imparted to the U-shaped strap 66 through the worm 15 and worm segment 16 and from said strap 66 to the tubular bearings 59 carrying the housings 60 at the outer ends thereof and in which housings the propeller shafts 10 are journalled.

In the form of invention illustrated in Figs. 7 to 10, the submarine body 20a carries a pair of forwardly positioned propellers 51a, similar to the propellers shown in Figs. 1 to 6 and a pair of laterally disposed rearwardly located propellers 22a, the top deck of the submarine body 20a having a cabin hood 25a and carrying a receptacle for a life float withthe receptacle covered by the hinged covers 21a while another receptacle carried by the top deck forwardly of the cabin hood 25a houses. a captive floatwith the receptacle closed by hinged covers 18. In this form of the invention, the propellers 51a are carried by shafts journalled in housings 68a at the outer ends of tubular bearings 59a and the shaft 58a journalled through said housings 59a carries a pair of bevelled gears Bia that are respectively engaged by pinions 62a driven by the separate motors Sta.

"The shaft 58a may be driven by either or both of the motors 6 5a under control of the clutch devices '55 associated with the motor .shaft carrying the pinicns 52a. A pair of U-shaped straps 66a has the shaft 58a journalled through the side legs thereof, the straps being adjacently positioned with the outer leg of each strap anchored respectively to the inner end of the adjacent tubular bearing 59a while the worm segment 16a is secured as at 11a to the adjacent legs of said U- shaped straps and between said legs. The worm 25o carried by the Worm shaft 12a imparts rotative movement to the housings 59a for changing the direction of pulling force of the propellers 5102.

As shown in Figs. 11 to 15, the submarine body 252) carries a pair of stabilizing vanes 31b at opposite sides thereof between the front and rear ends of the submarine, while transversely aligned pairs of vanes 44b and 50b are respectively carried forwardly and rearwardly of the stabilizing vanes 31 at opposite sides of the submarine and said vanes 44b and 50b are hingedly mounted at their forward ends as at 80. A pair of forwardly positioned propellers 51b is carried by the submarine and are adjustable in a manner as described in connection with the other forms of the invention. A life raft 36b is carried in the reoeptacle 30b suspended from the top deck 24b of the submarine body and the rabbetted meeting edges 8| of the cover sections 211) are retained in closed position by latch devices 33b carried by operating handles 34b which in turn are engaged with keepers 35b. A captive float 82 is normally confined within a receptacle 83 suspended from the top deck 24b of the submarine body, the cover sections 18b of the receptacle 83 being retained in closed position by means of latch devices 84 operated by handles 85 located interiorly of the submarine body. The captive float 82 is attached to one end of a cable 86 that is wound upon the drum 81 in the receptacle 83 so that when the latch devices 84 are released, the cover sections 18b of the receptacle 83 automatically open and the float 82 rises to the surface of the water.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent and while there are herein shown and described the preferred embodiments of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
